A structure of corners (4) comprising: three groups of direct expansion modulated frames forming a metal structure (4) providing through fixing elements and with oblong holes for assemblies (5, 6, 7, 8, 24) an individual expansion of each modulated frame (1, 2, 3) forming the floor bearing structure comprised of two glazing groups (12, 14, 15), the first of these two glazing groups having a flame-arrester function. The second glass group bears important loads, resting on an isolated panel (13) which is used for the perfect holding of the first glazing group and also has a thermal barrier between the two glaze groups. The low portions of this structure are isolated by means of a folded steel hood and isolated by alumina silica threads. The assembly is fixed to masonry walls through the oblongs holes by means of an assembly of fixing elements which provide for its holding and dilatory displacement.
